Genes affected
SCNN1B (HGNC:10600): (sodium channel epithelial 1 subunit beta) Nonvoltage-gated, amiloride-sensitive, sodium channels control fluid and electrolyte transport across epithelia in many organs. These channels are heteromeric complexes consisting of 3 subunits: alpha, beta, and gamma. This gene encodes the beta subunit, and mutations in this gene have been associated with pseudohypoaldosteronism type 1 (PHA1), and Liddle syndrome. [provided by RefSeq, Apr 2009]

Low renin, low aldosterone hypertension Pathogenic:1
Likely pathogenic, criteria provided, single submitterclinical testingGeneID Lab - Advanced Molecular DiagnosticsMar 10, 2018This variant results in an amino acid alteration, replacing an arginine(R) with a glutamine (Q) at position 563, written as p.Arg563Gln or p.Q889H. . in silico prediction algorithms does not provide uniform data regarding the effect of this change on protein structure and function, and it has not been reported in the Clin Var Database (NCBI National Library of Medicine, NIH) but it has been described in 16 alleles out of 121124, in the ExAC database, the majority (9) belonging to heterozygous carries of Latino origin. The variant has been associated with low-renin, low-aldosterone hypertension in South African black and mixed-ancestry individuals, the authors conclude that only a portion of subjects with the R563Q allele fully express the Liddle’s syndrome phenotype (J Hypertens. 2003 May;21(5):921-6). Moreover, there is a positive correlation with pre-eclampsia in this population (BJOG. 2006 May;113(5):595-8). -
